A blue spot is located on a rope. As a pulse passes by, what is the spot’s average speed during it’s traverse motion from equilibrium to the peak and back. Height of pulse = 0.15m, L of rope = 9m, mass = 0.55 kg, the pulse travels the length of the rope in 0.85s and it takes 0.15 for the full width of the pulse to pass by. Pulse width is 1.59m

Expert Solution

Height of pulse

Length of rope

Mass of rope

Speed of pulse

In the time taken by the pulse to pass by, the blue spot moves from equilibrium to peak and back. That is the spot moves through a distance twice the height of pulse

Time taken for this movement is

Hence average speed of blue spot

Two blocks with different mass are attached to either end of a light rope that passes over a light, frictionless pulley that is suspended from the ceiling. The masses are released from rest, and the more massive one starts to descend. After this block has descended a distance 1.20m , its speed is 1.50m/s . a. If the total mass of the two blocks is 16.0kg , what is the mass of the more massive block? Take free fall acceleration...

The accompanying data show spot speeds collected at a section of highway located in a residential area. (i) Using the student’s t test, determine whether there was a statistically significant difference in the average speeds at the 95% confidence level. (ii) Also report for before and after the following: mean speed, standard deviation, 85th percentile speed and percentage of traffic exceeding the posted speed limit of 30 MPH. (iii) using the data, draw the histogram frequency distribution, cumulative percentage distribution...
